Three quarter bed and mattress sizes in South Africa

A three-quarter bed gives one sleeper more room than a single without using as much floor space as a double. That balance makes it useful for teenagers, students, guest rooms and adults who sleep alone. Mattress Gallery offers both three-quarter mattresses and complete three-quarter bed sets so you can replace only the mattress or buy a matched sleep system. 

How big is a three-quarter bed? 

In South Africa, a standard three-quarter mattress is generally about 107 cm wide and 188 cm long. An extra-length version is generally 200 cm long. Product dimensions can vary slightly by manufacturer, and a base or frame is usually wider and longer than the mattress itself, so confirm the listed dimensions before ordering. 

Who should choose a three-quarter bed? 

• Teenagers who have outgrown a single bed but do not need a double. 

• Students or young adults furnishing a compact bedroom or flat. 

• Solo sleepers who change position often and want more elbow room. 

• Guest rooms that need comfortable sleeping space while preserving circulation. 

• Smaller main bedrooms where a double would restrict wardrobes, doors or walkways. 

Measure the room, not only the mattress 

Measure the full footprint of the frame or base and leave enough space to move around it. Check that cupboard doors, bedroom doors and drawers can open fully. Plan where bedside tables and plugs will sit, then mark the proposed bed outline on the floor with masking tape. This makes the remaining walking space easier to judge than measurements on paper. 

Standard length or extra length? 

A standard length may suit many sleepers, but taller people should consider extra length. Your feet should not rest against or hang over the end when you lie in a natural position. Before choosing extra length, confirm the room, frame, fitted sheet and mattress protector can accommodate it. 

Mattress only or complete bed set? 

Choose a mattress only when the current base is the correct size, supportive, level and in good condition. Browse the full mattress range if you are comparing constructions or comfort levels. Choose one of Mattress Gallery’s complete bed sets when the base is worn, incompatible or missing. A matched set removes uncertainty about fit and support. 

Comfort and support still matter 

Size determines usable sleeping space; it does not determine how the mattress feels. Consider your preferred sleeping position, body weight, temperature and whether you like a firmer or more cushioned surface. The goal is a mattress that feels comfortable while keeping your body supported in a neutral position. 

Bedding and protection 

Check that fitted sheets are labelled for a South African three-quarter mattress, especially when buying extra length. A correctly sized mattress protector helps guard against spills, moisture and everyday wear without bunching beneath the sheet. 

Delivery and access checks 

• Measure doorways, staircases, passages and tight corners. 

• Confirm whether the base is supplied in one piece or split sections. 

• Clear the route before delivery and decide where the old bed will go. 

• Compare the packaged dimensions with lift or stair access in flats and complexes. 

Common mistakes to avoid 

• Buying from mattress dimensions alone and forgetting the frame footprint. 

• Assuming every three-quarter product has identical measurements. 

• Keeping a damaged or sagging base beneath a new mattress. 

• Choosing standard length for a tall sleeper without testing it. 

• Buying bedding before confirming standard or extra length.
